阅读理解While football fans feel strongly angry about mistakes made by referees (裁判) because they cannot see clearly what has happened, a small German pany is quietly pleased. For Cairos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The pany has developed a tiny chip(芯片) that fits inside a football and determines whether the ball has crossed the goal line, by being able to discover its exact location on the field. The world football organization, FIFA, has shown interest in the technology. It is very possible that the new technology will be used in the 2006 World Cup in Germany.We've been testing the technology at the main soccer stadium in Nuremberg for some time and more recently in an under-17 FIFA Cup in Peru, said Gunter Rohmer, a director of the pany. The technology has performed well, and we're pretty optimistic that it will be used at the games in Germany next year.The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a second to a receiver network of 12 antennas(天线), placed around the field. The receivers then send information about the ball's location to a central puter, and because it works in real time, it can immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip in other ball sports.FIFA aims to test the technology later this year at another game in Japan before deciding whether or not to introduce it in all 12 stadiums in Germany for next year's World Cup.1.Carlos Technologies is pleased because ________.A.football fans are angry with refereesB.their new product can satisfy football fansC.their new product will have a good marketD.they can sell a lot of football in the future2.In the first sentence in Paragraph 2,... mistakes made by referees are the kind of advertising that money cannot buy means ___________.A.Carios Technologies can't afford the high price for advertising their productB.Mistakes in production are also a kind of advertisementC.Carios Technologies has already spent a lot of money on advertising their productD.Referees' mistakes will be of great help for the sale of Carlos Technologies' new product3.The underlined word feedback probably means ___________.A.information given back by a userB.advice given by someoneC.supplying food to customersD.food given back by consumers
